这是在tabcontrol中获取当前actve标签页的简单方法

here is a simple way to get the currently actve tabpage within the tabcontrol

TabPage ActiveTab()
{
    if (tabControl1.SelectedTab != null)
    {
        return tabControl1.SelectedTab;
    }
    return null;
}

这是获取当前活动的WebBrowser的简单方法.

here is a simple way to get the currently active WebBrowser

WebBrowser ActiveBrowser()
     {
         if (tabControl1.SelectedTab != null)
         {
             foreach (Control control in tabControl1.SelectedTab.Controls)
             {
                 if ((control) is WebBrowser)
                 {
                     return (WebBrowser)control;
                 }
             }
         }
         return null;
     }

现在要在活动选项卡中找到WebBrowser，只需使用此

Now to find the WebBrowser within the active tab just use this

WebBrowser Browser = ActiveBrowser();
        if (Browser != null)
        {
            // do what you need with the active browser here
        }
